. To all whom. it may concern:

Be it known that I, PETER 1B. Donanoo, citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Pivot-Lights, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to headlight operating means and the principal object of the invention is to provide a connection between the turning gear of a vehicle and said headlight so that the rays from the headlight will always be projected in the direction the vehicle is traveling.

In carrying out the objects of the invention generally stated above, it will, of course, be understood that the essential features thereof are necessarily susceptible of changes in details and structural arrangements, but a preferred and practical embodiment thereof is shown in the accompanying drawings, wherein- Figure l is a view in front elevation of a' portion of the front of a running gear for a vehicle showing the headlight operating device carried thereby. Fig. 2 is a horizontal sectional view taken on the line 22, Fig. 1. Referring to said drawings by numerals, l designates a front axle of a vehicle which has a knuckle joint connection 2 with a hub 3 of a wheel l. A spring 5 has been shown supported upon said axle, said spring carrying a lamp bracket 6 through which a vertically arranged shaft 7 projects. Said shaft 7 is rotatable in saidbracket and carriesthe usual lamp fork 8 for the lamp 9., The lower end of said shaft 7 projects beyond the bottom of said lamp bracket, and at its end is provided with a horizontally arranged plate flat intermediate bearin 10 which is connected to said end of a screw or bolt- 11.

The knuckle joint 2 at its up or end carries a rigid upstanding vertica y arranged pin 12 which is provided with a widened surface 13 resting upon said upper end 0 the knuckle joint, and above said bearing surface, said pin is by means in the form of a spool 14:, thaouterendof.

which is provided with an annular outstand ing collar 15 An endless cable 16 is passed around said spool 14 and the shaft 7 of the lamp fork, sald cable being held inengagement with said spool and said shaft by the staples 17 and 18. i

The fork 8 at its base is provided with an outstanding lip. 19 which is engaged by the bifurcated end '20 of a connecting rod 21, the other end of said rod having a similar engagement with a lamp fork on the opposite slde of the vehicle.

It will be seen from the foregoing that a turning movement of the steering wheel will simultaneously impart a similar movement to the headlight so that said headlight will project its rays in the direction the vehicle is traveling and as the lamp on the o osite side of the vehicle is connected wit the lamp that is operated by said steering wheel, both lamps Will rotate simultaneously.

It is preferred to use a cable formed of wire rope as the same is to a certain extent flexible and will slightly ield to the rocking or lurching of the vehiclie, so as to prevent damage being done to the operating cable, shaft and spool- What I claim as my invention is 1. A headlight operatin device for vehicles comprising a rotatable lamp support, a turning knuckle, a spool carried thereby and an endless cable fastened to said spool and said lamp support.

2. A. headlight operatin device 'comprisin a lamp support rotatably mounted on a ve icle, a spool rigid with a knuckle joint of a turninggear, and a cable fastened to said spool and said support.

3. A device of the character described I the combination with the turning gear of a vehicle provided with a knuckle joint, of a spool projecting above and rigidly connected In testimony whereof I hereunto aflix my to said joint, a lamp bglcket, a lamp sllllpport signature in presence of two witnesses.

rovided with a sha ro'ectin t rou h End rotatable in said brgcl et, a able 05% PETER DONAHOO' 5 nection between said spool and shaft, and v Witnesses:
